Dobby Layer
Stablecoin swaps hide more fees than you think. Dobby fixes it with fair execution.

Know what your stablecoin
trades & payments really cost.

Our analyzer estimates the value taken from mainstream centralized rollups, then compares it against our Dobby decentralized sequencer path with truly OS-level fair ordering. Connect your wallet or enter a trade to view the execution loss Dobby helps you take back.

Fair execution

Users often focus on the visible swap fee, but the larger cost can be hidden execution loss from MEV, slippage, failed trades, and reordering. Dobby fixes the gap.

Use a wallet-connected trade

Connect a wallet or paste an address, pick a supported chain, then choose one recent trade to prefill the forensic intake with a real tx hash.

Supported today: Base, Optimism, and Arbitrum explorer-backed swap candidates. Connect a wallet or paste an address, then load one trade for analysis.
Don't want to connect your wallet? Tell us about your trade!

You can still submit the trade manually, but the current forensic slice only works when you provide a real transaction hash on one of the supported chains.

This stores a forensic case locally or in Postgres, depending on environment configuration.
